如何在 JAX-WS Web 服务上引发自定义的 soap 错误?如何指定soap故障的faultCode
、faultString
和detail
?是否可以将 detail
的值设置为 bean 而不是 String
?
请注意,我正在使用代码优先方法进行开发。
最佳答案
使用 @WebFault
注释。
您可以在 Using SOAP Faults and Exceptions in Java JAX-WS Web Services - Eben Hewitt on Java 中看到一个很好的例子.
你会看到这个例子:
@WebFault(name="CheckVerifyFault",
targetNamespace="http://www.example.com")
public class CheckVerifyFault extends Exception {
/**
* Java type that goes as soapenv:Fault detail element.
*/
private CheckFaultBean faultInfo;
public CheckVerifyFault(String message, CheckFaultBean faultInfo) {
super(message);
this.faultInfo = faultInfo;
}
public CheckVerifyFault(String message, CheckFaultBean faultInfo,
Throwable cause) {
super(message, cause);
this.faultInfo = faultInfo;
}
public CheckFaultBean getFaultInfo() {
return faultInfo;
}
}
更新
另一种方法是在 throws
子句中声明典型异常。
例如假设以下是我的异常类:
package pkg.ex;
public class FooException extends Exception {
public FooException(String message, Throwable cause) {
super(message, cause);
}
}
下一个类是服务实现。
package pkg.ws;
import javax.jws.WebService;
import pkg.ex.FooException;
@WebService(serviceName = "FooSvc")
public class FooService {
public String sayHello(String name) throws FooException {
if (name.isEmpty()) {
Throwable t = new IllegalArgumentException("Empty name");
throw new FooException("There is one error", t);
}
return "Hello, " + name;
}
}
如果我的要求是:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ws="http://ws.pkg/">
<soapenv:Header/>
<soapenv:Body>
<ws:sayHello>
<arg0>Peter</arg0>
</ws:sayHello>
</soapenv:Body>
</soapenv:Envelope>
没有问题:
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:sayHelloResponse xmlns:ns2="http://ws.pkg/">
<return>Hello, Peter</return>
</ns2:sayHelloResponse>
</S:Body>
</S:Envelope>
但是……
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ws="http://ws.pkg/">
<soapenv:Header/>
<soapenv:Body>
<ws:sayHello>
<arg0></arg0>
</ws:sayHello>
</soapenv:Body>
</soapenv:Envelope>
那么……
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<S:Fault xmlns:ns4="http://www.w3.org/2003/05/soap-envelope">
<faultcode>S:Server</faultcode>
<faultstring>There is one error</faultstring>
<detail>
<ns2:FooException xmlns:ns2="http://ws.pkg/">
<message>There is one error</message>
</ns2:FooException>
</detail>
</S:Fault>
</S:Body>
</S:Envelope>
